Package: guvcview
Version: 1.7.3-2
Severity: important
Dear Maintainer,
opening guvcview leads to a black window as camera output, no image.
Camera is Logitech C910 and works normally with vlc and Qtv4l2
.
Changing beetween yuyv and mjpeg leads to black window output,any other
format makes the output window disappear until program is restarted.
Debug output :
